Angular2 - RC5 Http.delete fails

Question

Im upgrading my angular2 app to RC5 and now the Http.delete operation fails (before it gets executed) when it was succeeded before.

Here the package.json: "@angular/common": "2.0.0-rc.5", "@angular/compiler": "2.0.0-rc.5", "@angular/core": "2.0.0-rc.5", "@angular/http": "2.0.0-rc.5", "@angular/forms": "0.3.0", "@angular/platform-browser": "2.0.0-rc.5", "@angular/platform-browser-dynamic": "2.0.0-rc.5", "@angular/router": "3.0.0-rc.1", "@angular/router-deprecated": "2.0.0-rc.2", "@angular/upgrade": "2.0.0-rc.5",

Here is how Im using it:

deleteUser(id){
    let headers = new Headers({ 'Content-Type': 'application/json'});
    let options = new RequestOptions({ headers: headers });
    return this.http.delete(this._usersUrl + '/' + id, options)
         .map(res => { 
             return <User>res.json()
         })
        .catch(this.handleError)
}

While debugging I can see that it gets until http.delete and while executing the delete operation something crashes (DELETE is not sent to server). I have checked the docs for Http api in case I'm missing some arguments but I think they are fine.

Checking more carefully, none of the delete operations get executed but others HTTP operations work fine. Any clue?

The error I get is the following:
